The organophosphate, dichlorvous (Otapia-pia) formulated in varying concentrations as insecticides is utilized by several individuals in most remote places of Nigeria due to its affordable value and accessibility. However, this present study is conducted to investigate the adverse effect of the exposure of this substance on the respiratory system (lungs) of male albino wistar rats. Twenty (20) albino wistar rats comprising of all males weighing between 150-230g were divided into four groups (A-D) of five animals each. Group A received only water, feed, and served as the control. Group B was exposed to dichlorvous inhalation 3hrs daily for a period of two weeks; Group C was exposed to dichlorvous inhalation 6hrs daily for a period of two weeks; while Group D was exposed to dichlorvous inhalation 10hrs daily for a period of two weeks. Twenty four hours after the last exposure, the animals were sacrificed by cervical dislocation and dissected. The lungs were weighed and fixed in 10% formal saline for histological studies. The body weight of the experimental groups decreased insignificantly when compared with the control group. The lungs weight increased significantly when compared to the control groups. Histological observation revealed a moderate to severe effects on the lungs with severe consolidated inflammatory exudates (discharge of fluids from pores), a moderate intra-alveoli hemorrhage, and a severe dilation of alveolar septa which is evident as emphysematous changes. This result revealed that the exposure to dichlorvous causes distortion of the normal histological architecture of the lungs. Thus, showing that dichlorvous inhalation influences the normal physiologic mechanisms of the lungs.

In the search for medicinal plants that will provide ameliorative measure to patients with anaemic disorders. The methanol extract of O. gratissimum leaf was administered to Wistar rats for its effect on haematological profile. Twenty-eight (28) male Wistar rats ranging from 180-200g was randomly picked and placed into plastic cages labeled A-D. Group A served as the control group while groups B-D was the test groups. The  animals in group A was administered with distilled water orally by gavage. Group B were administered 50mg/ kg body weight of methanol extract of O. gratissimum, group C were administered with 100mg/kg bodyweight while group D were administered with 200mg/body of methanol extract of O. gratissimum for 14 days. Blood was collected from all the test rats and control by cardiac puncture using disposable syringe and needle then dispensed into tubes containing EDTA. The extract displayed a significant increase (p<0.05) in RBCs, Hb, PCV and platelet counts. More so, the  extract produced no significant (p>0.05)difference in MCV, MCH, MCHC and RDW WBC counts when compared with the normal control .Therefore, it will be logical to conclude that the extract of O. gratissimum might be a panacea in the management of anaemic conditions when properly harnessed due to its erythropoietic, haematopoietic and thrombopoietic effect. Keywords: Anaemia, erythropoietic, haematopoietic, thrombopoietic and phytochemicals.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

Abstract Introduction: Arteether™, a derivative of artemisinin, is among the recent drugs that have given renewed hope for combating malarial menace. The present study investigated the effects of arteether™ on the histology of the retina and cerebellum of Wistar rats. Materials and Methods: Twenty adult albino Wistar rats weighing 150-200 g, were randomly divided into four groups (A, B, C and D) of five animals each and used for this study. Group A rats were given intramuscular (i.m.) arteether™ (3 mg/kg b.w.) daily for 3 days. Group B rats were given i.m. arteether™ (6 mg/kg b.w.) daily for 3 days. Group C rats were also given i. m. of arteether™ (3 mg/kg b. w.) daily for 3 days, and the same dose was repeated at two-weekly intervals for 4 further weeks; while Group D rats which received normal saline (0.9 % w/v, 3 ml/kg b.w.), served as controls. At the end of the experiment, the rats were sacrificed by cervical dislocation. The retina and cerebellum were excised and processed routinely for histopathology changes, using haematoxylin and eosin stain (H & E), as well as Nissl stain. Results: Results obtained showed normal cellular components of the retina and cerebellum in all groups, and no cyto-pathological changes were observed. Conclusion: Thus, this study showed that under light microscopic examination, therapeutic doses of arteether™ caused no significant cyto-pathologic changes in the retina and cerebellum of Wistar rats.

An study was conducted on "Cobb-500" broiler chicks to evaluate the effects of probiotics and enzymes supplementation on growth performance, haematological and biochemical parameters. A total of 20, fourteen days old broiler chicks were divided randomly into four groups using five broiler chicks in each group. Group A was designated as control group was given only normal broiler ration and rest of the groups were fed probiotics and enzymes, [Group B (probiotic Microguard® @ 1 gm/L), Group C (enzymes preparation Acmezyme* 1 gm/L), Group D (Microguard* g 1 gm/L and Acmezyme @ 1 gm/L)] with drinking water respectively from 1St to 21st day of study. It was observed that probiotics and enzymes supplementation enhanced the body growth rate. At the final day of experiment the body weight was significantly increased (P<0.01) in the treated groups in comparison with that of control group. Total Erythrocyte Count (TEC), Hemoglobin (Hb) concentration, Packed Cell Volume (PCV) were significantly increased (p<0.01) in treated groups than the control group. Erythrocyte Sedimentation Rate (ESR) and Serum alanine aminotransaminase (ALT) levels were decreased significantly (p<0.01) than the control group. The serum Serum aspertate aminotransaminase (AST) level was decreased significantly (p<0.01) in all treated groups except group D than the control group. It is suggests that the poultry farming may be benefited using probiotics and enzymes. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18221 J. Bangladesh Agril. Univ. 11(1): 111-118, 2013

Cobalt induces hypoxia in the brain which leads to oxygen deprivation resulting in cognitive disturbance and decreased motor control. This study evaluated the effect of Moringa oleifera extract on the cobalt chloride-induced cerebral cortex of adult male wistar rats.  40 male wistar rats weighing (90 ± 120g) were used for the study and they were divided into 5 groups with each group containing 8 rats. Group A served as control which received distilled water, Group B was treated orally with Cobalt chloride at dose 45 mg/kg, Group C received cobalt chloride 45 mg/kg + low dose of Moringa oleifera extract 250 mg/kg for 52 days, Group D treated with cobalt chloride 45 mg/kg + high dose of Moringa oleifera extract 500 mg/kg and Group E treated with 500 mg/kg Moringa oleifera extract only and rats were sacrificed on the 53rd day by cervical dislocation. The brain of each rat was removed and weighed before half was fixed in formol calcium for histological analysis and the second half was used for oxidative stress parameters. The mean body weight of the wistar rats in group C and E increased significantly (P <0.05) while it decreased significantly (P <0.05) in group D. The biochemical analysis shows a significant increase (P<0.05) in the level of MDA in group B and a significant decrease (P<0.05) in group E. additionally, NO level shows a significant increase (P<0.05) in group B compared with control. SDH activity decreased significantly in group C, D, and E. Microscopic examination of the cerebral cortex in group B, C and D showed degenerative changes compared with normal histological features in A and E. The study concluded that cobalt chloride induced cerebral cortical damage while administration of Moringa oleifera extract attenuated the toxic effect of cobalt chloride in wistar rats.

Abstract: The plant Selaginella doederleinii is a herbal plant. Its phytochemical content including saponin, flavonoid and alkaloid can function as hepatoprotector. The objective of this study was to reveal the histopathological features of wistar rats induced with CCl4 and administered with water extract of the leaves of Selaginella doederleinii. This study was an experimental research employing 16 wistar rats. The rats were divided into 5 groups. Group A was the control group, whereas the other groups were treated with CCl4 for five days. The differences between these groups were as follows; after treatment with CCl4, rats in group B were terminated, rats in group C were fed with regular pellets, rats in group D were administered with water extract of the leaves of Selaginella doederleinii of 1.6 cc/day, and rats in group E were administered with water extract of  the leaves of Selaginella doederleinii of 3.2 cc/day. Results showed that the histological features of the liver of rats administered with water extract of  the leaves of Selaginella doederleinii for three days after treated with CCl4 exhibit numerous regeneration of liver cells. However, if the administration was prolonged for six days then fatty liver was observed. To conclude, Selaginella doederleinii can improve the histopathological features of the liver of rats induced with CCl4, however if the administration was prolonged then liver damage may occur. Keywords: Selaginella doederleinii, CCl4, histopathological features of the liver of wistar rats.   Abstrak: Tanaman cakar ayam merupakan sediaan herbal.

Objective: To evaluate weight changes on the liver of male (albino wistar) rats induced by erythromycin. To assess the outcome of aqueous Neem leaf extract on erythromycin induced hepatic injuries. Methodology: Eighty male albino wistar rats were taken randomly and were divided into 4 groups of 20 animals each. Group A as a control group. Group B rats were treated with erythromycin drug. Group C rats were treated with erythromycin along with Aqueous Neem leaves extract. Group D were given only Aqueous Neem leaves extract. Body weight of animals was recorded initially and also after experimentation. After 14 days animals were sacrificed, liver weight was also recorded. Results: The liver of erythromycin treated animals group B were little bigger in size and more reddish. However erythromycin plus Neem treated animals of group C livers were almost like liver of control group A and only Neem given group D animals, liver were exactly same appearance like control group A.Rise in absolute and relative weight of liver was because of drug toxicity. Conclusion: Its established from this recent study that Aqueous Neem leaves extract being a powerful antioxidant, decreased oxidative stress and hepatic injury caused by erythromycin.
